"Zzz..."
The walkie-talkie in the Salvation Army squad leader's hand crackled with interference, soon followed by an echo:
"I hear you, what's the situation?"
The captain immediately used the briefest words to inform the underground exploration team of the appearance of Lin Feng and the Holy Spring Sect Combat Priests, as well as their operational objective.
Due to the intense energy waves within the relics, any radio communication would be interfered with, so contact with the underground main force was only possible via wired communication.
Data line transmission is most resistant to interference.
However, the line had to extend several kilometers underground, requiring tens of kilometers of communication lines.
And at the other end of the line, in the Feicheng Shelter relic, six floors underground,
a group of more than ten people was stationed outside a large iron door, setting up a temporary camp.
